I want to know whether I can update my current Firefox version with my very old desktop setup. I am using the Firefox browser version 78.15.0esr (64-bit) on my iMac 2007 running OS X El Capitan. This notice came up when opening Firefox: " Your version of Firefox will start to have problems on January 14. A root certificate will expire, causing some preferences and other features to stop working. On March 14, 2025, add-ons and more features will also break." Following the instructions to update, in About Firefox window, it checks for updates and then shows Firefox is up to date. I've interpreted this as there's no version available that I can update to. Is that correct?

I use a 2009 Mac Mini running OS 10.11.6 dedicated for streaming. I was prompted to update Firefox to ESR which I did, replacing the older version of Firefox. The new version will not open.

It was the only browser I had. Can I undo the installation? Or download 78.15.0 somehow to restore the functionality of this Mac?

Hi My version of Firefox will not be supported after Jan 14th - I can't download an updated version of Firefox because my Mac is IOS 10.10 and apparently it needs to be at least IOS 12. What can I do? I will be updating my computer but I don't want to lose access to my docs etc on the 14th Jan. Thank you - I would appreciate help please.

I downloaded the latest version of Firefox. The directions tell me to open the file that i just downloaded, which is fine, except that I don't know the file name or location. What is it, and where is it? or how do I f find out?

Can MacOS High Sierra play Netflix? I cannot update to the most recent Firefox because my 2012 iMac cannot update to Catalina. Netflix says I need a new version of Firefox. How can I use Netflix on my iMac?

Hello,

I have an old version of MAC Os El Capitan 10.11.6, which new version of Mozilla can I install to respect new security standards ?

Thanks for your help

I got a password manager app but ended up uninstalling it. In the process, the normal insertion of my user name and password on accounts I use no longer happened. The information is still in my password file on my iMac, but when I access, for example, my bank, I have to enter my user name and password by hand. Before I tried the password manager (Roboform), there was no problem.

The "restore previous session" function stopped working today. My privacy and security sessions are set to REMEMBER HISTORY. I have restarted my Mac. I have the latest version of Firefox. Why does it no longer work?

Hello there, Could some please tell me how to find the path of the history containing folder in firefox115.18.Oesr? I mean something like: /Users/<votre_nom_utilisateur>/Library/Application Support/Firefox/Profiles/<nom_du_profil>/places.sqlite

thanks in advance Rab

Hello:

I have a new MacBook Air with the M3 chip. I cannot login to my Costco account on this Mac. I can log in using my old MacBook and my iPhone. I am using the same settings as the ones on my old Mac. What seems to be the problem? Is it the new chip?

Regards,

Moe

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

I have a 2012 MacBook Pro, still using maverick's … I tried to upgrade Mozilla and now it doesn’t work.

I am shy of what’s needed to run the latest Firefox version and I’m not able to buy a newer laptop, how can I get restated again with the version that will still work on my MacBook ?.
